"""Simple API for XML (SAX) implementation for Python.

This module provides an implementation of the SAX 2 interface;
information about the Java version of the interface can be found at
http://www.megginson.com/SAX/.  The Python version of the interface is
documented at <...>.

This package contains the following modules:

handler -- Base classes and constants which define the SAX 2 API for
           the 'client-side' of SAX for Python.

saxutils -- Implementation of the convenience classes commonly used to
            work with SAX.

xmlreader -- Base classes and constants which define the SAX 2 API for
             the parsers used with SAX for Python.

expatreader -- Driver that allows use of the Expat parser with SAX.
